This invention relates broadly to the class of plumbing and has as its object the expediting of the installation of plumbing fixtures, particularly such fixtures as are known as built-in 5 bath tubs so that the same can be connected, in one operation, with the installation of the roughing in of the soil and waste line, thereby eliminating all guess work with reference to roughing in measurements and at the same time provide ways and means for testing the tub connections simultaneously with the making of the soil test.

The invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawings wherein:

Figure 1 is a fragmentary view partly in section and partly in elevation illustrating the application of the invention with the plug in position incidental to the making of the soil test,

Figure 2 is a fragmentary detail sectional view taken substantially at right angles to Figure 1,

Figure 3 is a fragmentary top plan view illustrating the invention,

Figure 4 is a sectional View taken substantially on the line 4-4 of Figure 1, and

Figure 5 is a plan view of a metallic washer.

Referring to the drawings by reference numerals it will be seen that 5 indicates a fragmentary portion of a bathroom fixture, such as, for example, a stationary bathtub. The drain opening for the tub 5 is indicated generally by the reference numeral 6.

Disposed in alignment with the drain openmg 6 is an annular overflow chamber 1 that has an outlet neck 8 through the medium of which the chamber is connected with an overflow pipe 9 a portion of which is shown in the drawings.

Extending centrally through the overflow chamber 1 is a cylindrical casing H] which at its upper end is flared as at H and seats conformably within the drain opening 6 of the tub 5.

At the lower end thereof casing I is internally D threaded as at l2 for the threaded reception of one end of a nipple l3 through the medium of which the casing II) is connected with a conventional trap l4. Nipple 13 has an end threaded into the inlet end of the trap l4 as clearly shown in Figure l.

Inwardly from the flared end 6 thereof casing I0 is provided with internal threads l for the threaded reception of a strainer l6 that is provided with an outstanding flange ll that bears against the upper flared portion ll of the casing II] as shown.

Intermediate its ends the casing I0 is provided with an internal frustro-conical seat I! for accommodating a plug I8 that is adapted to be 5 used both as a test plug and a waste plug.

At the point where the strainer bars of the strainer I6 cross said bars are provided with a threaded opening Hi to receive a screw 20 that is adapted to bear against an apertured lug 2| provided on the top of the plug I8 for urging the plug l8 into tight engagement with the seat [1 when the plug I8 is to be used as a test plug.

When not in use as a test plug, plug I8 may be fitted within the strainer IE to serve, under such conditions, as a waste plug, When for plug I8 is thus used, the screw 20 is removed. Of course, the strainer I6 must be removed to permit removal of the plug 18 from the seat IT in the casing I0 for use as a waste plug in said strainer.

Above the seat I! casing I0 is provided at diametrically opposite sides thereof with overflow openings 22 through which the overflow may pass into said casing ID from the overflow pipe 9 and the chamber 1.

Completing the assembly is a lock nut 23 that threads on the externally threaded end 24 of the casing l0, and which when threaded home, serves to clamp between the bottom of the tub 5 and the nut 23 the overflow chamber 1.

Interposed between the top of the chamber 1 and the bottom of the tub 5 is a steel washer 25.

Disposed about the lower threaded end of the casing Ill is a rubber gasket 25 that has a central portion 21 that fits within the opening in the bottom of the chamber 1 and snugly about the lower end 24 of the casing ID for sealing the joint between the chamber 1 and the casing l0.

Interposed between the gasket 26 and the nut 23, and fitting loosely about the casing in, is a steel washer 28. Thus it will be seen that a fluidtight and leak-proof joint between the parts is provided for.

From the description of the invention it will be apparent that I have made provision whereby the drain opening in a bathroom fixed, such as a built-in tub, may be connected with the trap part of the soil pipe in a quick and eflicient manner, and also in such a manner that a single plug may be used to serve both as a test plug and also as the usual waste plug.

It is thought that a clear understanding of the construction, utility and advantages of an invention of this character will be had without a more detailed description thereof.

Having thus described the invention what is claimed as new is:

1. In a device of the character described, and in combination, a toilet fixture of the type embodying a drain opening, a trap, and a connection between the trap and drain opening, said connection consisting of a casing having a flared end fitting conformably within the drain opening of the tub and a second end adapted to be connected with the trap, a nipple connecting the second end of the casing with the trap, said casing adjacent the flared end thereof being provided with internal threads, and below said threads with an internal plug seat, a strainer provided with threads mating with the threads within said casing for securing said strainer within the flared end of the casing, and a plug adapted to engage said seat for use as a test plug, and also adapted to conformably seatwithin said strainer to serve as a waste plug. v

2. In a device of the character described, and in combination, a toilet fixture of the type embodying a drain opening, a trap, and a connection between the trap and drain opening, said connection consisting of a casing having a flared end fitting conformably within the drain opening of the tub and a second end adapted to be connected with the trap, a nipple connecting the second end of the casing with the trap, said casing adjacent the flared end thereof being provided with internal threads, and below said threads with an internal plug seat, a strainer provided with threads mating with the threads within said casing for securing said strainer within the flared end of the casing, and a plug adapted to engage said seat for use as a test plug, and also adapted to conformably seat within said strainer to serve as a waste plug, said strainer having the cross strainer bars thereof at the point where said bars cross provided with a threaded aperture, and a screw threaded through said aperture and adapted to bear against said plug when the latter is engaged with said seat for securing the plug engaged with said seat.

3. In a device of the character described, and in combination, a toilet fixture of the type embodying a drain opening, a trap, and a connection between the trap and drain opening, said connection consisting of a casing having a flared end fitting conformably within the drain opening of the tub and a second end adapted to be connected wtih the trap, a nipple connecting the second end of the casing with the trap, said casing adjacent the flared end thereof being provided with internal threads, and below said, threads with an internal plug seat, a strainer provided with threads mating with the threads within said casing for securing said strainer within the flared end of the casing, and a plug adapted to engage said seat for use as a test plug, and also adapted to conformably seat within said strainer to serve as a waste plug, an overflow chamber disposed in alignment with said drain opening and through which said casing extends, and said casing above said seat having overflow openings in diametrically opposite portions thereof for the passage of water from said easing into said overflow chamber.
